Summary
The Wizard's Castle is an 80s microcomputer BASIC game originally written for the Exidy Sorcerer platform. The source code includes a comment line that features a seemingly nonsensical string, which appears verbatim from the original code.
Key Takeaways
- The source code of the 80s microcomputer BASIC game The Wizard's Castle includes a mysterious string "_(C2SLFF4" that appears verbatim from its original publication in July 1980.
- The game uses the USR() function to call machine code routines, with specific memory addresses being manipulated through POKE commands.
- The Exidy Sorcerer BASIC interpreter tokenizes commands, converting them into single byte values for execution.
- The absence of a RANDOMIZE command in Sorcerer BASIC led to the necessity of using existing software or hardware for seeding the pseudo-random number generator.
